Most people on 4x4wire recommend only using OEM boot kits.  Go to yotatech.com and look up user TOR.  That's Todd who is the parts guy at Toyota of Richardson in texas.  He's got pretty good deals most of the time.   My boot kit cost somewhere around $25.  One boot kit will fix both the inner and outer boots of 1 axle.

Your next question is going to be how you get the stupid axle out in the first place.  The secret is to remove at least 2 of the 6 studs holding the axle on. 

Here's what I do, no need to remove the ball joints. All you do is:

1. disconnect the sway bar and shock.
2. Remove the upper bumpstop.
3. Remove at least 2 studs
4. jack up the truck by the frame or cross member.
5. Slide the axle out easily.

The most important thing is to remove the studs. You can grind/file down the splines and re-use them.
